Pada reaksi kesetimbangan:
CO(g) + 3 H2(g) ⇄ CH4(g) + H2O(g)
tetapan kesetimbangan untuk reaksi tersebut adalah … .
K = [CO][H2] / [CH4][H2O]
K =[CO][H2]3 / [CH4][H2O]
K = [CO][H2O] / [H2]3[CH4]
K = [CH4][H2O] / [CO][H2]3
K = [CH4][3H2] / [H2O][CO]

Persamaan reaksi kesetimbangan yang sesuai adalah ....
Al(OH)3(s) + 3H+(aq) ⇌ Al3+(aq) + 3H2O(l)
Al3+(aq) + 3H2O(l) ⇌ Al(OH)3(s) + 3H+(aq)
Al(OH)3(aq) + 3H+(aq) ⇌ Al3+(aq) + 3H2O(l)
Al3+(aq) + 3H2O(l) ⇌ Al(OH)3(aq) + 3H+(aq)
Al(OH)3(s) + 6H+(aq) ⇌ Al3+(aq) + 3H2O(l)
